Peanut Butter Cookie Pizza Crust

To make the peanut butter cookie crust, preheat the oven to 350°F and line a 12-inch round pizza pan with parchment paper. In a medium bowl, stir the peanut butter and sugars together until smooth. Both crunchy and creamy peanut butter would work. Beat in the egg. Then, stir in the baking soda, vanilla, and salt.

To roll out the crust, place the cookie dough on the parchment paper that is lining the pizza pan. Put another piece of parchment paper over the dough and with a rolling pin, roll out the dough to fit the pan. Remove the top piece of parchment paper and bake the cookie crust for 8-10 minutes, or until the center does not look wet. While the crust is baking, prepare the peanut butter sauce.

How to Make the Peanut Butter Sauce

To make the Peanut Butter Sauce, melt the butter and peanut butter over medium-low heat in a medium saucepan. Once they are fully melted and combined, add in the butterscotch chips. Remove from heat and stir continually until mostly melted. There will be chunks at the bottom of the pan, but that is not a problem. Set the sauce aside to cool a bit as you add the marshmallows to the crust.

Assembling the Peanut Butter Cookie Pizza

Once you have the peanut butter sauce made, the cookie crust should be finishing up baking for the first 8-10 minutes. Remove the crust and immediately add the miniature marshmallows to it. Turn the oven to broil and place the crust and marshmallows back into the oven for about a minute, or until the marshmallows just start to brown. Remove from the oven and top with the peanut butter sauce. Serve warm or at room temperature. Enjoy!

  1. I can’t even handle how amazing this sounds, Amanda! Pinned, Stumbled, and Tweeted!

  2. Oh. My. Word. I just cannot even comprehend this right now. Looks and sounds incredible!

  3. hi Amanda, in the instructions you say beat in the eggs, one at a time while there is only one egg in the ingredients…also instructions call for baking soda which is not on the ingredients list. the dough doesnt need flour? thanks for your advice

  4. Oh gosh, this looks amazing! I lovelovelove butterscotch and I’m so intrigued by this magical sauce! I need to try it. Love that you made a dessert pizza covered in marshmallows! Yumm. 🙂

  5. Oh.Em.Geee!!!
    This stuff looks like it should be illegal! Wouldn’t trust it to last 15 mins around here.

  6. Thank you so much for going with a recipe that does not utilize flour. I have celiac disease (no wheat, rye & barley) and although I’ve found a gluten free, cup for cup flour that works for most recipes, I always love finding recipes that don’t use flour. I am running to the store right now to get the ingredients for this amazing dessert! Thank you for your inspiration.

  7. I’m confused…how can it be the best dessert ever? There’s no chocolate.
    I’ll try it this way but I may have to add a chocolate dip or something cause well, it just seems wrong to have a p.b. dessert without chocolate:)
